Well sampling system incorporating corrugated and slotted injection system and method of use

Abstract

A device and method for collecting sample fluids from an underground source which includes sample wells terminating in a corrugated conduit and sieve. The sampling regions for each sample well is separated by a grout or expanding seal barrier. Negative pressure is optionally applied to extract fluids from the underground matrix for sampling. The device can also be used for remediating an environmental contaminant from soil or aquifers. Upon identification of at least one environmental contaminant, a remediation composition is injected into the soil or aquifer using the sampling wells of the device. The remediation fluids can be directed to specific locations by selectively utilizing one or more sampling wells to inject the remediation fluid.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of currently pending U.S. patent application Ser. No. 15 / 066,811 entitled, “Corrugated and Slotted Injection System and Method of Use”, filed on Mar. 10, 2016, which claims priority to U.S. Provisional Patent Application No. 62 / 130,988 entitled, “Corrugated and Slotted Injection System and Method of Use”, filed Mar. 10, 2015, the contents of which are herein incorporated by reference.FIELD OF INVENTION[0002]This invention relates to remediation injection systems for in situ remediation of contaminated soil and / or ground water. More specifically, the invention provides a novel system having a slotted corrugated device for removing liquids and / or injecting chemicals and / or biological material into soil or water using for remediation of contaminated soil and / or ground water.BACKGROUND OF THE INVENTION[0003]Environmental testing has become increasingly important, especially in locations where manufac...

Benefits of technology

[0012]In contrast to the known methods for sampling for contaminants from hazardous waste sites and other contaminated sites, the instant invention provides a method of soil/matrix sampling at multiple locations in the borehole, making the system less expensive, subs

Problems solved by technology

The storage of liquids and gases, particularly hazardous waste, the disposal of waste material and monitoring thereof were woefully inadequate for a large time.

Seeping of environmental contaminants has the potential to cause considerable harm to humans, both at the site of the contaminant, as well as distant sites, due to movement of water and other materials in the soil.

However, many commercial sites have structures, such as buildings, that limit access to the soil and groundwater.

Conventional testing requires excavation of the structure, such as drilling through the floor, which increases cost for testing, and can undermine the structure.

Further, hazardous waste site cleanup is a major environmental concern, with contaminants at many sites posing an immediate environmental concern.

Typically, these hazardous waste sites were created by the dumping of hazardous chemical
